Application led January 19. 1907. Serial No. 358,131.

To all 'whom 'it may concern.:

Be it known that we, CALVIN KEITH and GEORGE F. Lls'rnn, citizens of the United States, residing at Mansfield, in the county of Richland and State of Ohio, have invented certain -new and useful Improvements in Door-Hinges; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

`Our invention relates to that class of door hinges which permit the door to be swung in either direction.

It has for its object to provide a hinge which will assure free movement` of the door when in place` and which will permit the quick removal of-said door with out the necessity of first taking ouil sci'ews or the like and removing parts of the hinge from the door or casing.

, The invention consists ofthe features of construction and combinations of parts hereinafter described and specified in the claims. i l,

In the accompanying drawings, illustrating the preferredembodiment of our invention: Figure lis a broken elevation, partly in section, of a door and casing therefor,showing our hinge applied. Fig. 2 is an enlarged'vplan View of the tonguecarrying plate of the upper hinge which is secured to the door frame opposite the upper rear cornerof the door. Fig. 3 is a side elevation thereof. Fig. '4 is an enlarged perspective View of the swivel plate of the lower hinge which is secured to the lower rear corner of the door.4 F ig. 5 is an enlarged perspective view of the floor plate which is fastened opposite said swivel plate, and Fig. 6 is a central vertical sectional .view of said swivel plate.

Referring more particularly to the drawings,. 1 desig- A natos the door, 2 thefloor and 3 the door frame. The

upper hinge comprises a plate l4 secured to the door and having a projecting cylindrical lst'ud 5, and a tonguecarrying plate 6 securedto the door frame opposite said plate 4. Said plate G is provided with a slot 7 wide enough to receive the stud 5. The rear end of said `slot is rounded as at 8. A tongue 9 is pivoted between ears l0 on the upper surface of the plate 6 and extends into the slot 7 near the rear end thereof. The end of said tongue is grooved, as at V11, and forms with the rounded end of the slot a socket 12 for the stud 5. 'llre end of the slot is reinforced by a semi-circular flange 13 on the upper surface of the plate. Said tongue is-pressed-by aspring 14 and its movement is limited by a cross pin 15 inserted transversely through said tongue and adapted to Contact with the plate and stops 16 on the semi-circular flange 13. It will be noted 'that the outer end of the slot 7 is beveled, as at 17,

to permit the stud on the plate secured to the door to pass into said slot.

The lower hinge comprises the floor plate 1S secured to the floor opposite the rear bottom corner of the door, and a swivel plate 19 fastened to said bottom rear 'corner groove 20 in its upper surface, said groove being bisected by a longitudinal rib 2l preferably iuslrwith the surface of the plate. The swivel plate on the door carries a projecting lug 22 swiveled thereto by means of the pin or bolt 23. The upper portion of said lug, where it engages the swivel plate, is shaped like a truncated cone and is mounted in a correspondingly shaped bearing recess 24 in said plate. The lower face of said swiveled stud is curved from side to" side to fit the groove in the floor plate and is formed with a groove or way 25 having its bottom likewise curved or rounded to fit over the rib ou said floor plate and at .the same time permit the door to be tilted when hanging or removing it.

To hang a door which 1s equipped with our hinge, said'door-is turned at right angles to the plane of the doorway and tilted slightly while the swiveled stud 22 is placed in the groove in the Hoor plate. The door is then gradually brought to an upright position as the stud 5 on the top edge thereof is introduced into the slot of the plate 6. As said stud nears the inner end ofA said slot it raises thetongue 9 andfmally comes in contact with the curved end of'said slot whereupon said tongue drops into place behind it. To remove the door, it is again turned at right angles to the plane of the doorway whereby a portion of the slot in the plate Gis exposed. The tongue is then raised by means of a suitable tool inserted through said slot, thus releasing the stud 5 and permitting the doorto be tilted forward to entirely disengage said stud from said slot.

It will be noted the curved bearing between the of the door. Said fioor plate is provided with a curved swiveied stud and the groove in the floor plate allows the door to be tilted as described, while the rib on said floor plate engaging the groove or way in said Istud holds the latter in place. It will also be observed that the conical bearing between the swiveled stud and the plate carrying the same gives the door great freedom of movement.

We claim:
